Galaxy DX 2547 Problems

While most customers are delighted at their purchase, the radio does have a few downsides.

  • Few experts believe DX-2547 is not the ultimate choice for sideband communication. It needs to warm up for use, which eventually takes up a lot of time.
  • The Galaxy Noise Filter also seems to deliver an unsatisfactory performance, which can be a bummer!

How to add extra Channels in Galaxy 2547?

Here is how to add extra channels to your DX-2547:

Unscrew the bottom cover from your radio. Locate J33 on the mainboard. Next, situate wires on pins P5 and P6.

Cut the former and install an SPST switch in line. Repeat the process with P6.

What should I do when Galaxy DX-2547 squeals when receiving?

One primary reason for a squeal is when the microphone is placed too close to the speaker. It can also occur when the talkback function is adjusted to a loud setting. A sensitive mic can also result in squeal at the transmission.

Adjust the distance between your mic and speaker, and it should rid you of the problem. If you have an external speaker, turn its face away from you and turn on the noise filter.

How to turn up the modulation in a Galaxy DX-2547?

Here’s how to adjust the modulation on your Galaxy DX-2547:

  1. Turn up your transmitter’s wattage
  2. Adjust the modulation for max output
  3. Align the receiver to the ideal noise and signal ratio
  4. Alter the squelch range
  5. Modify the mic circuit for enhanced gain when required
  6. Adjust the transmit and receive meter
  7. Alter frequency to zero tolerance

After performing these tasks, the radio’s output typically increases by approximately 50%!


While base station CB radios have vanished from the scene, if there is one that continues to trend, it is the Galaxy 2547! While some may find it over-priced, we say, it is worth the investment given how feature-rich it is.

Keep in mind; this radio may not work for everyone. If you have space in your vehicle and money to spare, this one’s a pretty fun choice!
